Multifunctional locking device and servomotor with actuator which can be up wound up around an interchangeable reel

A multifunctional locking device and servomotor with actuator which can be wound up around an interchangeable reel wherein it is both a source of motion and a locking and monitoring device when connected to and becoming an integral part of the object or of a part of it and to an opposing point, comprising;

• an actuator as first fixing point, formed by a flexible section which can be rolled up to hold or draw back only or else comprises two sections to also thrust when these sections being identical and comb-like are forced to assemble opposed and staggered, outside the device, also at a distance from it, they become rigid whenever forced to go through a funnel-shaped combining head at the end of a sliding sheath comprising a fiber optics for each actuator's section and a multipolar cable for distance monitoring, the actuator being wound up around a reel which is a feature of the device, is made on purpose and is interchangeable acting at the same time as housing and as a means to wind up the actuator onto worm screw grooves, the reel is to be replaced whenever the thrust characteristic for the two actuator sections is wanted, wherein these two actuator's sections being pushed due to the grooves being deep enough to become their partial seating and wrought as two continuous winding groove spirals assembled opposite and onto mirror planes, located in the supporting case inside an appropriate hollow and centred through rotation pins on opposite bushes onto the supporting case closing lids, wherein this supporting case can move eccentrically in both ways when its actuator is forced either from its place or track, dampened at stroke limit against the containing box which includes all the components of the device and is also its last fixing point, wherein a mechanism fixed on the supporting case transforming the eccentric semi-rotations of the supporting case into the linear movement of a bolt getting in between the supporting case and its corresponding rotating part and blocking it, this being the toothing of a crown gear assembled next to a motorized gear with moving play, coupled to the reel onto the same rotation axis wherein also a second mechanism always fixed onto the supporting case transforming the semi-rotation allowed by the play of the above crown gear in order to draw back the bolt wherein a gear fixed onto a shaft for the connection to the engine-unit and the coupling to the engine-equipped gear is next to the crown gear.

A multifunctional locking device and servomotor with actuator which can be wound up around an interchangeable reel acting both as a protection and a sensor equipped security control, becoming automatically a mechanical locking device whenever a force is applied, this is obtained through a mechanical clamp acting onto the reel and thus on the actuator which is extensible and flexible until it reaches the application point, beyond that point it becomes stiff so as to either hold steady or become a source of movement for any object or mechanism connected with it, when acting as a lock the device is operated by an appropriate electronic key controlling the drive with a servomechanism and equipped with two manual security unlocking devices;

• if used as a servomotor it can be driven through a LAN network or an USB port, wherein the actuator can be split in two sections lengthwise which can be assembled or disassembled so as to be flexible when resting and stiff when in operation since the actuator is the means through which the device operates and functions in fact, when hooked to an object it becomes integral with it and functions as a safety bolt or a mechanical arm, if the actuator is very long, it can be ranged into an appropriate external box or it can be wound up and thus be stored into an appropriate spiral groove on the reel surface which is a main feature of the device;
• wherein the reel is easily replaceable and thus customized to any particular use, also different types of reels can be chosen:
• only to wind-up-gather or to draw back and thrust;
• wherein a sheath which can be formed by assembled parts or be a one flexible piece according to the type of actuator chosen is useful to reach points where the force has to be applied situated also at remarkable distances, the actuator slides inside its sheath and when it comes out changes and from being flexible and rolled around its reel it becomes rigid while passing through the special assembly head, a main feature of the of the device, which joins together in a reversible manner the two available sections of the actuator which are wound-up and which engage together in a sequence with the small ‘male’ teeth into the ‘female’ ones thus building up a column in different possible ways;
• wherein inside the actuator are hidden fiber optics and a multi-core cable or single wires useful for the measurement of environmental conditions, of events, housebreaking and stop limit stress, connected to optic or electronic sensors located in an electronic device rotating together with the reel and useful to collect and process data coming through the actuator to then transfer them via radio directly to the fixed resin-bonded card, besides the power connection is situated onto the reel pin, all data received also by the internal sensors on the case can be transferred at a distance via telephone or through wire or wireless networks by way of devices available on the market;
• wherein the pin hinging onto the containing box which is fixed while the supporting case moves as an eccentric having two adjacent and communicating cylindrical hollows apt to contain and connect respectively the reel to the actuator on one side and the hub to the clutch unit on the other, again both the drive gear and the blocking gear are keyed to the hub together with the small bolt inside a groove placed at arc radius and kept in place by a cover onto which—and hinged to the hub pin-pivots a double half-wheel gear used for reset, also a sealing bushing having a perpendicular through hole useful to the eye tension rod to slide in and also as a rest for a contrast spring pushing it towards the unit made up by the lever keyed to the sector gear engaged to the rack on the small bolt determining its position, the rod coming out of the central bushing, diagonal and at the opposite end of it, connects the locking bolt unit through another bushing similar to the previous one, anchored to another half-wheel gear engaged to the second toothing of the half-wheel gear and rotates round the pin connected to a free-release bearing fixed in an appropriate housing in the middle of an L shaped feeler lever connected to a feeler rod, side by side to each feeler are two springs onto strain gages placed at the exit points on the opposed edge stroke limits of the supporting case in two directions on to the containing box;
• wherein a free-release wheel into the reset gear keyed to the leading engine shaft, controls the turning direction and is chained to the double gear which makes the half-wheel gear rotate if this is engaged through the connection of the locking bolt control unit to take it to the release position when the engine is turned on;
• wherein a forked lever placed in the centre of the device, pivoting onto the supporting case next to the locking bolt engages the gear motility unit so as to move it away when the locking device is released manually;
• wherein the pulley wheel is overlapping and integral to and “eight” shaped cam used for monitoring through a trigger lever onto the hub clutch into the reel manual release;
• wherein a mechanism being the end part of an electromagnet fixed to the containing box so as to swing a long lever duly pivoted, it is parallel to the engine and opposite to a block interrupting the travel of the pulley which can be engaged or disengaged through the electronic key, again for the device manual release is a cylinder lock with mechanical key;
• wherein a mechanism is the tailpiece of a micro-contact checking the device operation;
• wherein a resin bonded electronic circuit monitors the functioning of the internal sensors as well as of the engine and acts as an interface for the connection with all external devices.
